Well,
I can only speak for the Model 37. The first one I saw was when I was maybe 4 years old, my grandfather hunted with it. My father has about 6 of them, and I have 2 of them. I have used it for everything from skeet to rabbit, squirrel, dove and deer. I have never had a failure in mine, nor has anyone in my family that has used them over the last 50 years.
I hope that helps you some.
Greg
